Blacks in the US have a reputation, for a reason Yellows too Whites too Arabs, pakis, kikes, muzzies, sikhs... And each reputation is different, for a reason I guess that reason comes from what they did and what they do, and the rest of the world watching them doing these things, gives a reputation So yeah, if I live in the US, and I'm a cop, and I get to pick a criminal in baskets of people, I would first single out all the males. Then, I would single out blacks and latinos from the remaining basket of males. Then I would pick one. Why? Because statistically I have more chances to pick a criminal like that. And that's what a pull over is, a control routine, it's a tad random by nature https://upload.wikimedia.org/wikipedia/commons/thumb/3/3a/US_Prisoner_Demographics.svg/350px-US_Prisoner_Demographics.svg.png And yeah, of course, last thing I would pick is a caucasian girl, statistically Doesn't mean that there's no criminal caucasian girls around though...
